(1) The amount of nylon and sleeve assembly seat more than the large amount of interference metal Daqing cast nylon tube, over 1 to 1.2% by the amount of interference diameter, so that the bush after bush pressed into the base with an appropriate tension to Anti loose. Generally quiet with the 0.10 ~ 0.15mm, extended cast nylon tube, moving with and within the range of 0.5 ~ 0.8mm. (2) with the size nylon sleeve and shaft have increased, the gap is 0.8 to 1.0% shaft diameter, pressed into the bush after bush can, nylon sleeve shrink still ensure adequate clearance and the shaft with, color cast nylon tube, otherwise the heat generated during operation axle phenomenon. (3) when the bush and the seat assembly using the penetration method, the lowest cast nylon tube, must beat hard-hit oil nylon Dezhou Wang Yue Composite Materials Co., Ltd. in the late 1980s, the introduction of advanced technology from abroad and the successful development of New product. The wear resistance can be increased by 10 times, it is not designed for lubrication, high load and low speed parts developed by oil nylon bearing life significantly improved, up to 6 times the normal nylon bearing life and phosphor bronze 25 times the bearing life! The maximum diameter cast nylon tube, Texas Wang Yue (online consultation), Daqing cast nylon tube by Wang Yue Dezhou Composites Limited. Wang Yue Dezhou Composites Co., Ltd. (www.dzshyfhcl.com) (www.dzshyfhcl.com) (www.dzshyfhcl.net) Shandong Dezhou, chemical products processing leader, over the years, the company implement the scientific management, innovation and development , the principle of honesty and trustworthiness, and satisfy customer needs.
